沿海地区复杂地质条件下高铁桥梁桩基础施工技术研究——以新建广州至湛江高速铁路工程为例

Research on Construction Technology of High-speed Railway Bridge Pile Foundation under Complex Geological Conditions in Coastal Areas——Taking the New Guangzhou-Zhanjiang High-speed Railway Project as an Example

目前,沿海地区复杂地质条件下,高铁桥梁桩基础施工依然存在诸多问题和不足,比如技术运用错误、设计未能结合实际情况等,对高铁桥梁整体的安全性和稳定性产生了不利影响。对此,文章结合新建广州至湛江高速铁路工程实例,梳理沿海地区复杂地质条件下的高铁桥梁桩基础施工流程,总结施工过程中存在的问题并分析问题产生的原因,最后提出了高铁桥梁桩基础施工的优化措施,以供参考。

At present, under the complex geological conditions in coastal areas, there are still many problems and shortcomings in the construction of high-speed railway bridge pile foundation, such as wrong technical application and failure to integrate the design with the actual situation,which have adverse effects on the overall safety and stability of high-speed railway bridges. In this regard, combined with the new Guangzhou-Zhanjiang high-speed railway project, this paper combs the construction process of highspeed railway bridge pile foundation under complex geological conditions in coastal areas, summarizes the problems existing in the construction process and analyzes the causes of the problems, and finally puts forward the optimization measures of high-speed railway bridge pile foundation construction for reference.
